NAME

       fence_cpint - I/O Fencing agent for GFS on s390 and zSeries VM clusters

SYNOPSIS

       fence_cpint [OPTION]...

DESCRIPTION

       fence_cpint  is	an  I/O Fencing agent used on a virtual machine running GFS in a s390 or zSeries VM cluster.  It uses the cpint package to
       send a CP LOGOFF command to the specified virtual machine.  For fence_cpint to execute correctly, you must have the cpint module installed,
       and hcp in your PATH.  NOTE: for fence_cpint to send a command to another virtual machine, the machine executing it must either be a privi-
       lege class C user or it must be the secondary user of the virtual machine to be fenced.	This means that unless	all  of  you  GULM  server
       nodes are privilege class C, fence_cpint can only be used with SLM.

       fence_cpint accepts options on the command line as well as from stdin.  fence_node sends the options through stdin when it execs the agent.
       fence_cpint can be run by itself with command line options which is useful for testing.
